I put two sets of batteries in already, each only lasting one week. The batteries were the best you can get. In the week that it worked, it worked fine. I put it in my closet, the light would come on when I opened the door, but after a week, both times, the batteries went dead.

I use it when I let my dogs out at night. It is very bright and easy to handle. I bought it to put above my front door, but it won't stay on (it turns itself off) so it wasn't any good to me that way, but it is wonderful to have in the car when I get home and it's dark, or as I said to let the dogs out at night.
